本発明の多層プリント板は、プリプレグ上に形成される
位置決め用基準穴を、プリプレグを構成する織布の織目
方向と対応させることによって、多層プリント板の積層
時に発生する歪を低減させた点に特徴がある。Detailed Description of the Invention [Summary] The multilayer printed board of the present invention has a positioning reference hole formed on the prepreg that corresponds to the weave direction of the woven fabric constituting the prepreg. The feature is that the strain that occurs during lamination is reduced.

ト板積層時の歪を減少させた多層プリント板に関する。The present invention relates to an improvement in the structure of a multilayer printed board, and particularly to a multilayer printed board that reduces distortion during lamination of printed boards.

含浸させたものであることは周知のとおりである。As shown in FIG. 4, the multilayer printed board is composed of a pair of upper and lower surface layer materials 2, at least one prepreg 4, and an intermediate layer material 3. Note that the prepreg 4 is inserted between the intermediate layer material 3 and the surface layer material 2, or between the intermediate layer material 3 and the surface layer material 2.
As is well known, the bonding material is disposed between the intermediate layer material 3 and the bonding material, and is made of a woven fabric 4a whose base material is glass fiber or paper fiber, etc., impregnated with an adhesive.

り、多層プリント板に歪が発生する。However, the shrinkage rate of the woven fabric 4a constituting the prepreg in the warp direction (direction of arrows AA') during lamination is much larger than that of the surface layer material 2 and the intermediate layer material 3. Shrinkage stress acts on the circular reference hole 6 of the surface layer material 2 and the intermediate layer material 3 through the guide pin 1, causing distortion in the multilayer printed board.

が長い変形基準穴7になっている。[Means for Solving the Problems] The multilayer printed board of the present invention has a central pair of reference holes in the prepreg 4 disposed between the surface layer material 2 and the intermediate layer material 3. The circular reference holes 6 into which the guide pins 1 are inserted in the fitted state are the same as in the past, and the holes are formed at both ends in the longitudinal direction (arrow A-A'') of the standard size of the multilayer printed board, that is, in the warp direction. The other two pairs of reference holes are deformed reference holes 7 in which the dimension in the warp direction is longer than the dimension in the weft direction (arrow B-B' direction).
